SMIGHT

Stations can only be created by users who have ‘Superuser’ and ‘Station Administration’ user rights. Before SMIGHT Grid2 can be installed in the station on site, the station must be created with the outputs in Device Admin so that the outputs can be linked to the sensor ID and the station to the gateway ID during installation on site.

Enter general data about the station and its location in Deviceadmin. Configure the outputs and add an additional low-voltage distributor if necessary. If you want to create multiple stations, you can use the Excel import function. A template is available in Deviceadmin for this purpose, which you can download, fill out and then upload again.

Users can only be created by users who have the user rights ‘Superuser’ and ‘User management’. Users are created in Deviceadmin. In addition to entering general data, user rights and network area, you must set an initial password for the new user. The password is not automatically sent by the system. You must provide the user with this password together with the user name and instruct them to set a new password.

If you want to create multiple users, you can use the Excel import function. A template is available in Deviceadmin for this purpose, which you can download, fill out and then upload again. Please note that network areas must be assigned to each station and each user. If you do not want to use network areas, please use the ‘Standard’ network area.

Network areas can only be created by users who have the user rights ‘Superuser’, ‘User Administration’ and ‘Station Administration’. The network areas are created in Deviceadmin by specifying and saving the name. It is possible to correct or change the network area name at a later date. In order to be able to see the station, the network area must be assigned to the user and the station area.

Stations can only be deleted by users who have ‘Superuser’ and ‘Station Management’ user rights. Deletion is carried out in Device Admin. To delete a station and the associated departures, select it from the overview and use the ‘Delete’ button. A pop-up will appear asking whether the station should actually be deleted. This must be confirmed with Yes. When the station is deleted, all data collected so far in the SMIGHT IQ web portal will also be deleted.

Users can only be deleted by users who have the user rights ‘Superuser’ and ‘User management’. Deletion takes place in Deviceadmin. To delete a user, select them from the overview and use the ‘Delete’ button. A pop-up will appear asking whether the user should actually be deleted. This must be confirmed with Yes.

Network areas can only be deleted by users who have the user rights ‘Superuser’, ‘User Management’ and ‘Station Management’. Deletion is carried out in Device Admin. To delete a network area, select it from the overview and use the ‘Delete’ button. A pop-up will appear asking whether the network area should actually be deleted. This must be confirmed with Yes. A network area can only be deleted if no user or station is assigned to it.

1. User account is activated.
2. The initial password has been changed and a new password assigned. To do this, use the Deviceadmin desktop application or the SMIGHT IQ web portal.
3. Additional user accounts have been created in Deviceadmin as required.
4. Stations have been created in Deviceadmin.
5. The SMIGHT Grid Installer app has been installed.

In the app: The gateway and sensors are assigned when the grey radio icon appears in the station row on the SMIGHT Grid Installer app home screen. Once the radio icon turns green, data transmission has begun.

In Deviceadmin: The gateway and sensors are assigned when the status of the stations changes from ‘Ready for installation’ to ‘Ready for configuration’. If the status shows ‘Ready for operation’, the data is transferred to IQ.

In IQ: If a station is visible in the SMIGHT IQ web portal and measurement data is available for it, the gateway and sensors are registered and the data is transferred.

The SMIGHT Grid Installer app is available for Android and iOS. You can download the app from the Google Play Store or the Apple App Store.

Ensure that your initial password has been changed in the Deviceadmin desktop application or in the SMIGHT IQ web portal. You can only log in to the app with the password you have set.

• Check whether the station has been created in Deviceadmin beforehand. Only then will the stations be visible in the app.
• Check whether the corresponding network areas have been assigned to you in Deviceadmin.
• Once you have ensured that the stations have been created and the network areas have been assigned correctly, we recommend repeating the registration process in the app.

Depending on the type of station and the number of outlets, the installation itself takes approximately 30-60 minutes. If additional preparations are required, such as installing new sockets for connecting the gateway, the installation time may be longer.

Depending on the order, the hardware delivery may include the following components: Grid2 Gateway, Grid2 Sensor, Grid2 Sensor Flex, Grid2 Power Supply, tool set, extension cable and operating instructions.

The tools required for installation are side cutters, screwdrivers and drills, and a plastic wedge for working under 1,000 V AC voltage. Optional materials include dowels, cable ties, screws and a Schuko socket. Depending on the type of station, additional tools and materials may be required.

No. The direction is indicated by the arrows labelled ‘Trafo’ and ‘Netz’ on the sides of the transformers.

The QR codes are located on the type plates of the gateway and the sensors.

This information is essential for the correct calculation of the active currents. The connected phase and the direction of the rotating field are determined using a two-pole voltage tester.

The diameter of the Grid2 sensors with folding transducers allows for a maximum cable cross-section of 230 mm², although we recommend use up to 185 mm². The Grid2 Flex sensors with Rogowski coils allow for a maximum cable cross-section of 300 mm².

Während der Installation müssen die gültigen Arbeitssicherheitsvorschriften des Netzbetreibers berücksichtigt werden. Eine persönliche Schutzausrüstung gemäß DIN EN 50110-1 (Schutzkleidung, Handschutz, Fußschutz, Geschichtsschutz) sollte getragen werden.

The app displays the status of the station to the left of the station name.

Setup: The station has not yet been set up and no hardware has been assigned to it. The QR codes on the gateway and sensors must be scanned using the app and transferred to the SMIGHT Grid2 backend.

Waiting for connection: A gateway and sensors have been assigned to the station. A connection to the SMIGHT Grid2 backend has not yet been established. If the status does not change to ‘Connected’ after a maximum of 5 minutes, the app must be refreshed by pulling down the station list. If the status does not change, check whether the gateway is receiving power.

Connected: The gateway is connected to the SMIGHT Grid2 backend. Measurement data can be sent.

Inactive: Data transmission to the SMIGHT Grid2 backend is paused because no gateway is assigned anymore (e.g. due to a hardware replacement). The old data remains visible in the SMIGHT IQ web portal.

In Deviceadmin: The status of the station can be seen in the ‘Status’ column. The following statuses exist:

Ready for installation: The station has been created in Device Admin and is ready for installation.

Ready for configuration: The station has been installed and scanned, but no data has been transferred yet.

Ready for operation: The station has been installed and is transferring data.

Inactive: The station has been removed, the collected data is stored long-term and can still be viewed.

The SMIGHT Grid2 web applications can be used in all common web browsers. We recommend Google Chrome, Microsoft Edge, Apple Safari and Mozilla Firefox.

Note: Please do not use Microsoft Internet Explorer. As this browser is outdated, the SMIGHT Grid2 web applications cannot run correctly.

Our hardware monitoring allows us to detect failures at an early stage. If you encounter any problems, please contact our support team:

The gateway contains a multi-roaming SIM card, which allows most stations to operate even with poor mobile network coverage. Mobile network coverage of at least 2G (Edge) is sufficient to transmit the measurement data to the SMIGHT Grid2 backend.

In general, SMIGHT Grid2 hardware is maintenance-free. To ensure smooth operation, a visual inspection of the gateway and sensors should be carried out as part of the mandatory DGUV inspection (max. 4 years) or as part of the inspection intervals specified by the network operator for the station (approx. 5 to 8 years).

You will receive monthly reports for the network areas you have selected.

The aim of the individual reports is to give you a quick and well-founded overview of your network area.

They provide you with information at a glance about the utilisation of all measured stations and outlets. The 10 outlets with the highest relative utilisation compared to the fuse value are also displayed. The report also contains the top 10 stations with the highest absolute utilisation.

The SMIGHT IQ Cockpit home page provides you with a quick overview of the most heavily utilised stations and outlets.

• The map uses a traffic light system to quickly show you which stations have heavily utilised outlets in the selected period.
• The colour coding of the traffic light system is as follows:
  • Green: No outlet at the station has reached more than 60% utilisation of the fuse value during the selected period.
  • Yellow: At least 1 outlet shows a utilisation of 60-80% of the fuse value.
  • Red: At least 1 outlet shows a utilisation of over 80% of the fuse value.
  • Grey: The station has been set to ‘Inactive’.
• Below the map, you can see the maximum station and departure utilisation for the selected period, sorted in descending order in tiles. In addition, all events that occur when the threshold value or fuse value is exceeded are displayed.

The station level provides you with a quick overview of the output and total currents as well as the single-phase measured voltage of the gateway.

• The output tiles display the maximum utilisation relative to the fuse value, similar to the traffic light system on the start page. Each output has one of the following statuses:
  • Online: The output has transmitted data in the last 60 minutes.
  • Offline: The output has not transmitted any data in the last 60 minutes (e.g. due to currents being too low for energy harvesting).
  • Unassigned: No sensor has been installed on this output.
• The total current is divided into effective current and active current (only available for Grid2). The data is aggregated in 15-minute intervals, with the maximum value for each interval being displayed.
• The total effective current is calculated by adding the active and reactive currents and forming the effective value. The active current is summed taking into account the sign.

On the output level, you can display the phase-accurate data measured by the SMIGHT sensor technology in relation to active and effective current. These values are also displayed in relation to the defined threshold value. The aggregation of the data is adjusted depending on the selected time period, with scaling down to 1-minute measurements possible. In addition, the load distribution for the selected time period can be visualised.
